Sorting an array of Objective-c objects
- by davbryn
So I have a custom class Foo that has a number of members:
@interface Foo : NSObject {
NSString *title;
BOOL taken;
NSDate *dateCreated;
}
And in another class I have an NSMutableArray containing a list of these objects. I would very much like to sort this array based on the dateCreated property; I understand I could write my own sorter for this (iterate the array and rearrange based on the date) but I was wondering if there was a proper Objective-C way of achieving this?
Some sort of sorting mechanism where I can provide the member variable to sort by would be great.
In C++ I used to overload the < = operators and this allowed me to sort by object, but I have a funny feeling Objective-C might offer a nicer alternative?
Many thanks
